The present invention relates to an improvement of a coin dispensing device that dispenses according to the situation.
[0002]
[Prior art]
Conventionally, in vending machines, money changers, service devices, etc., it is possible to determine whether the coins are correct or not, and to select and store the input coins that are regarded as genuine coins for each denomination. A coin processing device is arranged to pay out the amount according to the amount of change.
[0003]
This coin processing device is roughly divided into the following three elements.
[0004]
The 1st is a coin sorter which discriminates the true / false of the inserted coin, and sorts a pure coin for every denomination.
[0005]
The second is a coin storage device that is arranged below the coin sorting device and is composed of a plurality of coin tubes that each store the genuine coins sorted by denomination by the coin sorting device.
[0006]
The third is a coin dispensing device that selects and dispenses coins according to the amount of change from within the coin storage device.
[0007]
Among these, the conventional coin dispensing device 1 has a structure as shown in a fragmentary conceptual perspective view of FIG.
[0008]
This coin dispensing apparatus 1 includes a drive motor 2, a gabox 3 in which gear transmission means (not shown) for transmitting the drive force of the drive motor 2 is disposed, and an illustration in the gabox 3. A pair of payout cams 4 and 5 that rotate in one direction (clockwise) for each payout operation by a driving force transmitted through the gear transmission means, and pins projecting from the lower surface of the payout cams 4 and 5 A payout link 6 that has grooves 6a and 6b that engage with 4a and 5a, and when the payout cams 4 and 5 make one rotation in the direction of the arrow (clockwise), reciprocate in the direction of arrow A from the initial position in the figure The payout link 6 is detachably engaged via a pair of pins 6c and 6d, and is composed of a payout slide 7 that reciprocates in the direction of arrow A in conjunction with the reciprocating motion of the payout link 6. The above-described drive motor 2, gabox 3, payout cams 4, 5 and payout link 6 constitute a payout slide drive device.
[0009]
The payout slide 7 is formed with holes 8, 9, 10, and 11 for receiving only one coin stored on the lowermost surface of each coin tube (not shown) constituting the coin storage device. The bottom surfaces of the holes 8, 9, 10 and 11 always cover the bottom surface of the payout slide 7 at the initial position in FIG. 9, and the coins stored in the holes 8, 9, 10 and 11 are dropped. A bottom plate 12 of the coin dispensing device is provided for blocking.
[0010]
On the other hand, in the payout link 6, the tip faces the lower surface of each hole 8, 9, 10, 11 of the payout slide 7, and coins stored one by one in each hole 8, 9, 10, 11 are stored. Change slides 13, 14, 15, and 16 that control the payout and non-payout are inserted and retracted.
[0011]
Of these change slides 13, 14, 15 and 16, the tip 13a of the change slide 13 is in the hole 8, the tip 14a of the change slide 14 is in the hole 9, and the tip 15a of the change slide 15 is in the hole 10. A tip 16 a of the slide 16 is disposed so as to face the hole 11.
[0012]
Further, the rear ends of the change slides 13, 14, 15, 16 are represented by the rear ends 13b, 14b, 15b of the illustrated change slides 13, 14, 15 as shown in the drawings. , 16 are engaged with change levers 17, 18, 19, 20 constituted by plungers of change solenoids 21, 22, 23, 24 arranged independently of each other, and their movements are restricted at all times. Yes. Of the change solenoids described above, the change solenoid 24 constituted by the change solenoid 24 and its plunger is not shown.
[0013]
According to the above-described coin dispensing device unit 1, for example, when a signal for dispensing one coin stored in the hole 8 is input, the payout cams 4 and 5 are moved to the arrows by the rotational force of the motor 2 based on the signal. The payout slide 7 is reciprocated in the direction of arrow A by rotating once in the direction, and the coins accommodated in the holes 8, 9, 10, 11 of the payout slide 7 are one by one. The change lever of the change solenoid 21 for restricting the movement of the rear end 13b of the change slide 13 based on a signal for paying out one coin accommodated in the hole 8 at that time. 17 is operated and moves upward as shown by arrow B to disengage the rear end 13b of the change slide 13 so that only the change slide 13 slides backward in conjunction with the movement of the payout cam 6. Moved, thereby to maintain the opening of the bottom surface of the hole 8, the contained coins Therefore bore 8 is paid out and falls down the hole 8.
[0014]
The other change slides 14, 15, 16 have their rear ends regulated by the change levers 18, 19, 20 so that the bottom surfaces of the holes 9, 10, 11 are inside the change slides 14, 15, Each of the tips 14a, 15a, 16a of the 16 is not opened and the coins accommodated in the other holes 9, 10, 11 can be moved to the holes 9, 10 even if the payout slide 7 reciprocates in the direction of the arrow A. It does not fall out from the bottom surface of 10, 11 and is not paid out.
[0015]
That is, in the coin dispensing device 1 described above, if the change levers 17, 18, 19, and 20 corresponding to the coins to be dispensed are operated (up), the movement restriction of the change slide corresponding to the coins to be dispensed is released. The coins can be paid out. Of course, when paying out a plurality of coins of the same type, the change lever of the change solenoid corresponding to the coin is actuated (moved upward) to release the restriction of the change slide, and then the payout slide 7 is moved by the number of payouts. It is only necessary to reciprocate, and when multiple types of coins are to be paid out simultaneously, the change levers of the multiple change solenoids corresponding to the multiple types of coins are actuated simultaneously (up), and multiple types of coins to be paid out If the restriction of the change slide corresponding to is canceled, the plurality of types of coins can be paid out simultaneously.
[0016]
[Problems to be solved by the invention]
By the way, according to the conventional coin dispensing apparatus 1 described above, in order to dispense various types of coins, the number of change solenoids that function as change lever driving means is required corresponding to the type of dispensed coin. That is, in the conventional example of FIG. 9, it is necessary to arrange four change solenoids (change solenoids 17, 18, 19, and 20) corresponding to the holes 8, 9, 10, and 11 that respectively accommodate four types of coins. For this reason, the number of parts and the number of assembly processes are increased, which causes an increase in the cost of the entire coin processing device, and also requires a plurality of change solenoids to be selectively operated, which complicates the control. It was.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a coin dispensing device according to the present invention will be described in detail.
[0020]
FIG. 1 is a fragmentary conceptual sectional view of a coin processing device 26 equipped with a coin dispensing device 25 according to the present invention, and the same parts as those in FIG. In FIG. 1, a payout slide 7 connected to the payout cam 6 via pins 6c and 6d is not shown.
[0021]
This coin dispensing device 25 is also arranged for each change slide 13, 14, 15, 16 and engages with each rear end of each change slide 13, 14, 15, 16 when coins are not paid. When the coins are to be paid out, the change levers 17, 18, 19, and 20 that release the engagement with the rear ends of the change slides 13, 14, 15, and 16 and allow the movement thereof are used. A change lever driving means 30 for moving the change levers 17, 18, 19, 20 up and down is disposed above.
[0022]
The change lever driving means 30 has a single shaft 31 rotatably supported on the upper portions of the change levers 17, 18, 19, and 20, and the change lever fixed to the shaft 31 and having a corresponding peripheral surface. A plurality of cams 32, 33, 34, 35 that are in sliding contact with the respective heads 17 a, 18 a, 19 a, 20 a of 17, 18, 19, 20, and a ratchet mechanism 36 that rotates the shaft 31 in one direction by a predetermined rotation angle. And a ratchet mechanism driving means 37 for driving the ratchet mechanism 36.
[0023]
Next, the structure and operation of the plurality of cams 32, 33, 34, and 35 described above will be described using the cam 35 slidably contacting the head 20 a of the change lever 20 as a representative.
[0024]
As shown in FIG. 2, which is an enlarged side view of the main part of FIG. 1, a pair of small-diameter portions 35 a formed on the peripheral surface of the cam 35 fixed to the shaft 31 at a predetermined interval along the circumferential direction. 35b and a pair of large diameter portions 35c and 35d formed between the small diameter portions 35a and 35b are formed.
[0025]
According to the cam 35 having such a circumferential surface shape, when the circumferential surface of the large-diameter portion 35d of the cam 35 is in sliding contact with the head 20a of the change lever 20, the change lever 20 is resisted against the urging force of the return spring 40. Pressing downward, the lower end 20b protrudes from the change lever guide hole 41 and is engaged with the rear end 16b of the corresponding change slide 16 to restrict its movement. Similarly, when the large-diameter portion 35c of the cam 35 comes into sliding contact with the head 20a of the change lever 20, the change lever 20 is pressed downward to restrict the movement of the change slide 16.
[0026]
On the other hand, as shown in FIG. 3, when the shaft 31 is rotated by a predetermined rotation angle by the ratchet mechanism 36 and the small-diameter portion 35 b of the cam 35 is in sliding contact with the head 20 a of the change lever 20, Since the change lever 20 protrudes upward and its lower end 20b is retracted into the change lever guide hole 41, the engagement with the rear end 16b of the corresponding change slide 16 is released and its movement is allowed.
[0027]
Similarly, when the small-diameter portion 35a of the cam 35 is in sliding contact with the head portion 20a of the change lever 20, the change slide 16 is disengaged and allowed to move.
[0028]
Next, the ratchet mechanism 36 that rotates the shaft 31 to which the plurality of cams 32, 33, 34, 35 (FIG. 1) described above are fixed in one direction by a predetermined rotation angle will be described in detail.
[0029]
As shown in FIG. 2, the ratchet mechanism 36 includes a ratchet gear 45 fixed to the side of the shaft 31, and a ratchet gear 45 that engages with the ratchet gear 45 and rotates the ratchet gear 45 in a counterclockwise direction (implementation). In the example, the drive claw 46 is rotated by 45 degrees, the rotation restricting claw 47 for restricting the rotation of the ratchet gear 45 so that the ratchet gear 45 does not rotate more than a predetermined rotation angle, and the reverse rotation of the rotated ratchet gear 45.
